JBoss AS 7 migration - java.lang.ClassNotFoundException: org.hibernate.validator.ClassValidator

hibernate jboss seam jboss7.x

I have an application running on JBoss AS 4.2.3 and am trying to migrate this to JBoss AS 7.0.2. I am also upgrading seam from 2.1.1 to 2.2.2. I have resolved a few of the class not found exceptions, but I am stuck on

java.lang.ClassNotFoundException: org.hibernate.validator.ClassValidator

My full stack trace is below.

I'm not very clear on the new class loader in AS 7. Does Hibernate 4 work with seam 2.2.2? I have tried specifying the exports in jboss-deployment-structure.xml to use org.hibernate and org.hibernate.validator. However, when I look in the jars in these locations, I do not see the ClassValidator class...

I have also tried adding hibernate 3 jars to the EAR/lib and specifying them in the manifest, but that does not change anything. I see that hibernate 3 hibernate-validator.jar does contain the classValidator class, but it still doesn't find it.

UPDATE I also tried hibernate-validator-legacy-4.0.2.GA.jar

hibernate-annotations-3.4.0.GA.jar
hibernate-commons-annotations-3.1.0.GA.jar
hibernate-core-3.3.0.SP1.jar
hibernate-validator-3.1.0.GA.jar

Classloading model changed in JBoss 7. It hides much stuff that's not explicitly declared.

You have to get familar with these links:
